yes, you are correct, the beginning of the file seems to be the culprit. there appears to be a duplicated frame or two that's throwing the whole thing off. while this is a lenghthy process, I seem to have fixed one of them - this is what I did (and this has to be done on a Linux machine - not sure how well this software works on windows):

1) converted the MPEG2 to a DIVX;-) with mencoder from MPlayer
2) That initial conversion seems to fix it because it doesn't demux the audio and the video
3) then use transcode to convert back to whatever MPEG you want

while this worked for me, I can't guarantee it will work for everyone.

Interesting...

I might try to transcode the files and re-upload them to see if that fixes the problem.

In case you're interested, these are the command lines I used for the conversions. I'll use insect_to_injury.mpeg as an example.

Conversion to DIVX;-)...
mencoder -o insect_to_injury.avi -ovc lavc -oac lavc -ofps 29.97 insect_to_injury.mpeg

Conversion to MPEG...
transcode -i insect_to_injury.avi -y ffmpeg --export_prof dvd-ntsc --export_asr 2 -o thx -D0 -E 48000 -b 224 -s2 -m insect_to_injury.ac3

Multiplex audio & video...
mplex -f 8 -o insect_to_injury-new.mpeg insect_to_injury.m2v insect_to_injury.ac3

and voila! you have a dvd-ready MPEG2 file with proper audio and video sync.

ooops... messed up the Conversion to MPEG line... here is the correct line:

transcode -i insect_to_injury-new.mpeg -y ffmpeg --export_prof dvd-ntsc --export_asr 2 -o insect_to_injury -D0 -E 48000 -b 224 -s2 -m insect_to_injury.ac3

grrr... did it again...

transcode -i insect_to_injury.avi -y ffmpeg --export_prof dvd-ntsc --export_asr 2 -o insect_to_injury -D0 -E 48000 -b 224 -s2 -m insect_to_injury.ac3

that one's correct - I promise - that's what I get for copy and pasting without getting enough sleep first ;-)

Yes, I know, I tried - the system just seems to hang whenever I try it.
